1. A forward axle air spring strut for guiding a wheel in a motor vehicle having a chassis, the air spring strut comprising:

  • an air spring including;

    an air spring cover defining a longitudinal axis;

    an air spring piston; and

    , an air spring flexible member connected pressure-tight and tension-tight between said air spring cover and said air spring piston;

    a shock absorber integrated axially into said air spring;

    said shock absorber including;

    a shock absorber cylinder; and

    , a shock absorber rod axially displaceable and rotatable in said shock absorber cylinder;

    a non-rotatable elastic support connected to said chassis and said shock absorber rod being articulately connected to said chassis via said non-rotatable elastic support;

    said non-rotatable elastic support and said air spring cover conjointly defining an interface;

    a rotational bearing for connecting said air spring to said chassis separately from said shock absorber;

    said rotational bearing being mounted at said interface so as to permit said air spring to rotate about said longitudinal axis relative to said non-rotatable support and said shock absorber;

    a seal also mounted at said interface;

    said rotational bearing and said seal being mounted so that said bearing and said seal can be subjected to torsion when the wheel is turned for steering said motor vehicle;

    said cover, said piston and said air spring flexible member conjointly defining a pressure space;

    said seal being mounted above said rotational bearing; and

    ,said rotational bearing being mounted in said pressure space of said air spring.
